Lock device

Abstract

Lock device (1) which incorporates a closure assembly (2) that can move between an open position and a closed position, a locking device to lock said closure assembly (2) in the closed position, a first actuator (3, 31) and a second actuator (4, 41), both the first actuator (3, 31) and the second actuator (4, 41) having a locked position, in which a locking or retention action is applied, and an unlocked position, both the first and the second actuators having respective control devices which allow orders to be given to change the position of each respective actuator, wherein the first actuator and the second actuator are arranged in such a way that unlocking the locking device requires that both control devices place their respective actuator in the unlocked position.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority to European Patent Application No. 18382608.0 filed on Aug. 13, 2018, the disclosure of which including the specification, the drawings, and the claims is hereby incorporated by reference in its entirety.FIELD OF THE INVENTION[0002]The present invention relates to a lock device. More particularly, the present invention relates to a novel arrangement which has numerous advantages, including improving the operation of security locks or anti-panic locks, preferably in a small-size format, with regard to load situations, although this is only one of many advantages.[0003]The present invention may be applied to a wide range of lock devices, for example electric door openers, security doors, evacuation route doors and anti-panic doors, although the invention is not necessarily limited to said applications.BACKGROUND OF THE INVENTION[0004]Conventionally, door-opening devices have a single actuator (usually a coil)...

AI Technical Summary

Benefits of technology

The invention allows for separation of two actions using two independent actuators, allowing for maximum performance for each action. This also allows for the separation of energy supplies, which can result in the combination of actuators with different types of energy supply. A spherical projection and recess design is used for preloaded opening retention. The technical effects of the invention include optimised system performance and flexibility in energy supply options.

Problems solved by technology

In this situation, with the passage of time, the parts wear owing to the abrasion produced when preloaded opening occurs; this wear favours opening while compromising the locking function, and therefore it could indicate that in the long term the system is inefficient.

Since the system works using a tripping pin which is moved to the closed or open position by a very sensitive spring, and because the system is unidirectional, the mechanism functions better or worse depending on the position thereof in the installation.
